Irregular extracting stop and restarting operation
Screws taken out before the set number results in an irregular extracting and the machine stops.
For restarting, do as follows.
Reset the PLC to the original, desired operation.
After detecting an irregular extracting, it remains in OUT1 and so must be reset to the original desired operation.
[OUTPUT/INPUT colored areas are Low output.]
